LED ASSEMBLY FOR AUTOMOBILE REAR LAMP

摘要

PPROBLEM TO BE SOLVED: To provide a technique for using not less than two LEDs separately controllable for a common reflector to provide various functions, such as a stop light, a tail light, a blinker and the like. PSOLUTION: The present invention provides various techniques for combining not less than two LEDs in a single reflection type cavity to be used as an automobile rear lamp. The LEDs have not less than two different colors to provide various functions, such as a stop light, a blinker, a tail light and the like. In one embodiment, LEDs have side radiation lenses and are arranged coaxially in a parabolic reflector. The LEDs are mounted in one direction to face each other or so that they are combined. The LEDs share a common heat sink. A second reflector can be disposed in a larger reflector, a first LED is mounted in the vicinity of the focus of the larger reflector, and a second LED is mounted in the vicinity of the focus of an inner reflector.
